Brainboxes ED-527 16 Digital Output Device Server

SKU CH-RB0V-5F376 MPN ED-527

Ethernet device server provides 16 digital outputs and an RS485 gateway for industrial automation

  • Control 16 digital outputs remotely
  • Operate reliably from -30°C to +80°C
  • Connect via 10/100Base-TX Fast Ethernet
  • Integrate using Modbus TCP or simple ASCII
  • Mount directly on DIN rail for factory use

Industrial control gateway

The Brainboxes ED-527 provides sixteen digital outputs plus an RS485 gateway port for factory-floor process control and automation. It mounts on a DIN rail and operates across a -30°C to +80°C temperature range. The unit connects via 10/100Base-TX Fast Ethernet and supports simple ASCII or industry-standard Modbus TCP commands. Software APIs for Visual Basic, C# and other languages integrate with existing development tools.

Automation engineers and system integrators

This device suits engineers who need reliable Ethernet-to-digital-output conversion for industrial machinery, test rigs or building-management systems. The wide temperature rating and rail mounting make it practical for cabinet installation in harsh environments. Buyers who require Power over Ethernet, wireless connectivity or USB interfaces should look at alternative hardware because those features are absent.

Sixteen digital outputs and RS485

The defining specification is the combination of sixteen digital outputs with a single RS485 serial port on one Ethernet device server. This output count and gateway function determine whether the ED-527 matches the I/O requirements of a specific control application.

Questions about this item

How do I verify the 16 digital outputs are switching correctly after connecting the ED-527 to the network?

Apply power, connect the Ethernet cable, then use the COM-port driver or Modbus TCP to toggle each output while measuring voltage at the terminals.

What ships with the ED-527 and what must I source separately?

The unit includes the device server with integrated DIN-rail mount and a lifetime warranty; you must supply Ethernet cabling, a 10–30 V DC power source and field-wiring connectors.

Which ED-527 version suits a -30 °C to +80 °C cabinet with Modbus TCP control?

The single listed ED-527 model covers that temperature range, offers 16 digital outputs plus an RS-485 gateway port and supports Modbus TCP out of the box.
